Pretty much, except HQ is reported to be temporary barracks or something like that. There weren't any reports on high ranking or not so high Turkish officers being killed there as far as I know. Presumably photos of that place from the video where they were hit.

While Turks struck a meeting of Syrian officers
An Turks didn't take the gloves off completely. They still let "Orsk" through the Bosphorus and can close it for warships only with Montreux convention's article 20-21 wich requires pretty much declaration of war or smth close.
